In 1.1 b3, upload, install emulating 1.0, and check everything's ok, click install but then at: /index.php?action=admin;area=packages;sa=install2;package=QRR.v.105.elkarte.ahrasis.com.zip;pid=0
The addon: http://www.elkarte.net/community/index.php?topic=1822.0
Other addons faced the same error.
I tried again and there are at least five errors:
+ topic solved, recent post, bookmaks 1.1 b3 not work
Well, currently I am just looking for fixes to these errors. I cannot test or upgrade addons if they cannot be properly installed. However, I just realized that the addons are installed though they are not listed as installed in Package Manager as their settings are then available in Addons Settings. They are however listed as not found in Integration Hooks and this has been reported earlier I think.

You even took notice of that. :P
I remember it before but then totally forgot about it. Thank you for pointing it. It is now resolved.
